COTTON-GIN.

SPECIFICATION forming part Of Letters Patent NO. 242,763, dated June 14,1881.

Application filed April'Q, 1881. (N model.)

To all whom it may concern i Be it known that I, VALENTINE K. EDGAR, ofChico, in the county of Wise and State of Texas, have invented certainnew and useful Improvements in Cotton-Gins; andl do hereby declare thatthe following is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same, reference being had to the accompanying drawings,which form a part of this specification.

This invention relates to an improvement in cotton-gins; and it consistsin the features of construction and combination hereinafter fully I 5described, and particularly pointed out in the claims. In the 'drawings, Figure l is a side elevation of the machine embodying myimprovement, and Fig. 2 is alongitudinal section taken on a verticalplane.

A indicates the frame of the gin-stand, and B the saw-shaft. The usualgin-saws will be provided, and also the usual rotary brush which takesthe cotton from the saws.

0 indicates an inclined endless belt of fine wire-gauze, upon which thecotton is carried up to the condenser, the sand and dirt being siftedthrough this belt. 7 r

The condenser is formed by a roller, D, arranged just above the upperroller, E, around which the endless wire-gauze belt travels, and belowsaid roller E is arranged arotary wiper, F. Motion is transmitted tothese rollers and the wiper by means of a worm-gear, Gr, upon thesaw-shaft, and a shaft, H, having at one end a gear, I, engaging saidworm-gear, and its remaining end a gear, K, which intermeshes with alarger bevel-gear, L, upon the shaft of the roller E, around which theendless belt.

of bat without additional devices; but when said roller is small andlight spring-bearings can be employed for its journals.

The wire-gauze or wire-cloth band is bound along its edges with strips Rof oil-cloth or leather, so that the band will fit the box or case inorder to keep the air from exhausting near the edge, which wouldotherwise cause the cotton to get in around the edges of the wire-cloth.The upper band-roller is provided with longitudinal channels, and theendless band is provided with slats S, properly spaced,

so as to come into said channels during operation. I 1

I am aware that a rotary wire-gauze cylinder has been employed in acotton-gin but I find far better results are obtained by the use of theWire-cloth endless band herein illustrated the cotton being cleanedbetter by means of the long belt, and the lint is laid smoother 7o andstraighter thereon; also, the draft of the brush will not be obstructed,there being suffi cient space for the exhaust through the wiregauze.

What I claim, and desire to secure by Lot ters Patent, is

1. Ina cotton-gin, the endless wire-gauze band or apron, bound at itssides with strips R of flexible material, such as leather, as hereindescribed, for the purpose set forth.

2. In a cotton-gin, the endless wire-gauze band C, bound at its edgesand provided on its inner side with slats, in combination with thesaw-shaft, the condenser-roller D, and the upper roller, E, around whichthe band passes, 8 5 provided with longitudinal channels, as specified.

3. The combination, in a cotton-gin constructed substantially asdescribed, of the endmy own I have hereto affixed my signature in 5presence of two witnesses.
